Fluke LIQ-100-IE LINKIQ Cable and Network Tester

Keep industrial networks running with the Fluke LIQ-100-IE LinkIQ Cable and Network Tester — a purpose-built tool for OT technicians, integrators and IT teams responsible for security, surveillance and monitoring systems. By focusing on cabling — the leading cause of Industrial Ethernet failures — LinkIQ helps you prevent unscheduled downtime and accelerates fault resolution. The tester identifies miswired and split pairs on RJ45, M12X/M12D and M8D terminations, validates performance for Ethernet/IP, PROFINET and EtherCAT, and displays switch details (name, port and VLAN) for faster troubleshooting. Built for field use, it’s powered by a Lithium‑Ion battery and supports universal charging (100–240V AC), delivering reliable runtime and rapid readiness between shifts. LinkIQ also verifies PoE delivery with load testing and checks IP connectivity to gateways and DNS servers, ensuring surveillance cameras and monitoring devices get the power and network access they need. Capture and archive test results with LinkWare PC for documentation and compliance. Deploy the Fluke LIQ-100-IE to streamline commissioning, reduce mean time to repair, and protect production — order now or contact sales to integrate it into your network maintenance workflow.
